Thanks for playing the game and for the feedback. Appreciate it :)
The initial gun (or the gun when there are no gun drops available in the arena) spawn nearby the center. I couldn't fix a specific a place for the gun spawn because the whole arena is destructible, but I'll try to make the gun spawn more prominent (maybe a drone fly by that drops a loot box or something). However, an indicator will appear on the screen pointing towards the nearest gun when you're empty handed.
I have uploaded an updated version of the game, with (I think) better graphics, UI/UX and hitbox and hurtbox issue resolved, so I hope you will get a chance to give it another try and share your feedback. Thanks.
